  "raw_text": "The sealing tool was built on `age`, chosen because it transparently handles the Ed25519-to-X25519 key conversion and ChaCha20-Poly1305 encryption, allowing files to be sealed to the user's existing SSH/Ed public key. Because `age` was available in apt but required a sudo password the agent could not supply, the installation decision was deliberated between a no-sudo static-binary drop into `~/bin` versus the apt route; the user chose apt to rely on Ubuntu's already-trusted package mirror, keeping the privacy posture intact since keys and files remain local regardless.",
